All on one keyring:
Victorinox Manager - includes knife, nailfile, flat screwdriver, ballpoint pen, scissors, tweezers, cap lifter, magnet, Phillips screwdriver and wire stripper.
Fenix E15 - there are police officers still using flashlights ten times the size and weight that don't throw as much light as this, and you can use lower settings to conserve power if you want.
NiteStik tritium marker (same as in OP's pic).
Fox40 micro whistle.
A real tiny toolkit, and always carried with me because carrying keys is entirely habitual. The Manager's knife blade covers the cutting tasks of normal life well enough such as opening packaging and cutting thread, but a folding pocket knife can be added if needed. No-one will ever question or give strange looks at a 58mm Victorinox, air travel notwithstanding.
